Travis Smith answers:

@Ram, I don't believe that will work as it is missing a file or two containing the class and the widget.

Since Templatic developed the ecommerce as part of the theme, I would recommend talking to them or searching their community forums.

If I were you I would try using this plugin: [[LINK href="http://wordpress.org/extend/plugins/currency-converter/"]]Currency Converter[[/LINK]]

And if that doesn't work, you could also try using this plugin from WP E-Commerce ([[LINK href="http://getshopped.org/fpt-plugins/wpec-multi-currency-magic-plugin/"]]Multi-Currency Magic[[/LINK]]).
